In economics, cargo or freight are goods or produce being conveyed â generally for commercial gain â by ship, boat, or aircraft, although the term is now often extended to cover all types of freight, including that carried by train, van, truck, or intermodal container.
What are 'Consumables'. Consumables are goods used by individuals and businesses that must be replaced regularly because they wear out or are used up. They can also be defined as the components of an end product used up or permanently altered in the process of manufacturing, such as semiconductor wafers and basic chemicals.
A consumable item that is useful to people but scarce in relation to its demand, so that human effort is required to obtain it. In contrast, free goods (such as air) are naturally in abundant supply and need no conscious effort to obtain them. See also good.
